Brazing Copper Sheet

The choice between soldering or brazing generally depends on the operating conditions of the system and the requirements of the governing construction codes.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. Brazing is a metal joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint the filler metal having a lower melting point than the adjoining metal. Fluxing is an essential step in the brazing operation aside from a few exceptions. In actual practice for copper systems most soldering is done at temperatures from about 350 f to 600 f while most brazing is done at temperatures ranging from 1100 f to 1500 f.

Brazing is a quick and inexpensive alternative to welding. The equipment in this project can be bought for as little as 30 dollars. However the major differences are the following. In brazing and welding fabricators add a filler metal into the joint.

The filler metal can be aluminum silicon brass bronze copper copper silver gold silver nickel alloy or silver. The phosphorus in these alloys acts as a fluxing agent on copper.

Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces themselves. Use a torch that produces a high intensity flame. The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process while also requiring much.
